Summary
Brief summary
This study aims to implement a targeted 4CMenB immunisation program in young people aged 14-19 years in the Northern Territory (NT). As part of the NT program consenting 14-19 year olds will receive 2 doses of the licensed 4CMenB vaccine. An oropharyngeal swab will be collected on the same day as the first dose of the vaccine and 12 months later to assess carriage of Neisseria meningitidis. The first swab will assess baseline carriage prevalence among 14-19 year olds in the NT. The swab taken 12 months later will provide data on the change in carriage that may occur after implementation of the immunisation program. Emerging evidence suggests that the 4CMenB vaccine may be protective against gonorrhea. Therefore, vaccine effect (impact and effectiveness) against both invasive meningococcal disease (IMD) and gonorrhea in the NT will be assessed using data from the above study comparing notifications between vaccinated and unvaccinated as well as comparing pre and post implementation periods.
